Definitions

  • the present invention relates to the X-ray inspection of wheels, e.g. Alloy wheels.
  • Wheels e.g. Alloy wheels are safety parts that are 100% or fully inspected for defects by manufacturers or service providers. This is done in fully or semi-automatic X-ray inspection systems using X-rays. For this purpose, the wheel is positioned between an X-ray source and an X-ray detector and brought into different positions or position orientations with the aid of a manipulation system in order to be able to cover the entire volume of the test object during a test process.
  • the particular problem with the handling of the wheel is on the one hand to make a secure and relatively accurate positioning of the wheel or the wheel blank to be examined during the test process, and on the other hand to achieve a high positioning speed to the test time, i. the time required for the test process to minimize.
  • Systems based on the gripper technique include a conveyor system such as a roller belt, a manipulator with a gripping system and an x-ray device consisting of an X-ray tube and an X-ray detector.
  • the wheel is passed through the conveyor system through the test facility.
  • the X-ray tube and the X-ray detector are located above the transport plane or transport level defined by the conveyor system.
  • the beam direction between the X-ray tube and the X-ray detector runs parallel to the conveying or transport direction.
  • the manipulator realizes four axes, with respect to which the wheel during a test can be changed in its position, ie a Y-axis which is perpendicular to the transport direction parallel to the transport plane, for lateral displacement of the wheel, a Z-axis or vertical axis, the is perpendicular to the transport plane, for lifting the wheel of and depositing the wheel on the conveyor system, a pivot axis p, which extends along the Y-axis, for rotation of the wheel about the Y-axis and a rotation axis ⁇ of the wheel for rotation of the wheel or specimen about its axis of rotation.
  • the rotation and rotation axes are realized by the gripping system which is mounted on the manipulator to be displaceable along the Y and Z axes.
  • the gripper consists of four bevel wheels which grip the wheel on the horn of the rim of the wheel to be tested at the transport level or in the transport plane and bring it into the beam path between the x-ray tube and the x-ray detector by lifting and swiveling.
  • the individual angles of view or the angle of the beam path with respect to the wheel by continuous or, in the context of a stop-and-go mode, incremental start of the various Rotation angle ⁇ set.
  • the wheel is stored again on the conveyor or transport system and then transported away.
  • the gripper must be moved in the vertical direction to release the conveying path.
  • a second type of system is based on a chain conveyor technology.
  • the conveyor system and the gripping system are combined in a chain system.
  • Two circumferential chains which grip the wheel laterally at the lower horn of the wheel, take on the one hand the transport of the wheel through the test system, on the other they realize the X-axis of the manipulator, which corresponds to the Z-axis of the systems described above. Since the beam axis is vertical, i. perpendicular to the transport plane, and thus runs perpendicular to the transport direction, the chain transport can also take over the function of the axis of rotation ⁇ . In this case, the chains are moved in opposite or opposite directions.
  • the X-ray emitter and the X-ray detector are mounted opposite one another on a C-frame, which enables a rotation of the beam path defined by the X-ray emitter and detector about the transport direction axis.
  • a lateral displacement along the Y-axis either the C-frame along the transport plane is moved perpendicular to the transport direction, while the chain conveyor is not moved, or vice versa.
  • a disadvantage of the systems based on the gripping technique is that for lifting and dropping the wheel to be tested from or on the transport system, a considerable mechanical and temporal effort is required.
  • a disadvantage of the systems based on the chain conveyor technique is that in these systems, the risk of emigration of the wheel consists of the two circumferential chains of the chain system. This emigration is triggered for example by casting burrs or decreasing chain tension and may cause the wheel to be tested leaves the test area or the test facility. Consequently, stable testing is not ensured in these systems. In addition, these systems take up much space due to the necessity of rotating the beam path around the transport direction by means of the C-frame, and the pivoting range is limited to less than 360 °, depending on the design of the C-frame.
  • the US 4,949,366 refers to the X-ray inspection of automotive tires.
  • the tires to be tested are conveyed on rotatable rollers of a conveyor to swivel conveyor units which tilt the tires to be tested about an axis out of their transport plane as defined by the conveyor. In this vertical test position, they are transilluminated from the center by a horizontally displaceable x-ray tube, whereby the radiation outside the tire is picked up by diodes. Rotation of the wheel about its axis during fluoroscopy is also provided. After the test, the tires are pivoted back to the transport plane and transported by a discharge section 1.
  • the US 4,809,308 describes a method and apparatus for performing automated circuit board solder joint quality verification.
  • a circuit board to be tested is positioned on a translation device to pass through a door in the interior of a housing to be moved under an X-ray source, which then irradiates the board in the direction of a camera.
  • an XY positioning stage is implemented in order to be able to move the circuit board transversely to the direction of transmission during the transmission.
  • the table is mounted on a rotating table that allows a 360-degree turn of the table. Furthermore, the possibility of tilting the arrangement of rotation, positioning table and translation device from the horizontal is provided in an inclined plane and the ability to move the arrangement in the Z direction. After checking, the board is ejected again from the opening.
  • the JP 60-104240 describes a tire X-ray inspection device.
  • the tires to be tested are transported on a conveying path to a tire receiving base, where they are grasped by a pushing and depositing device, lifted, moved to a test location and lowered there again to a test position to which an X-ray source, an X-ray detector and a coil are placed. that the X-ray source does not form an obstacle to the tire to be examined.
  • the X-ray source can thus always remain in its position, which increases the accuracy.
  • the wheel is raised again, moved to a discharge conveyor, deposited on the same and then transported by the same.
  • the FR 901.717 refers to a fluoroscopy system for large castings.
  • This system it is possible to change the corresponding with a screen fluorescent tube in the height, at a distance to the screen, and to pivot about a vertical axis, ie in height directions. That to be screened Casting is driven on a support frame between the X-ray tube and the fluorescent screen.

  • the present invention is based on the finding that the advantages of the two aforementioned systems, namely the carrying out of the test in the transport plane in the systems of the chain conveyor type on the one hand and the safer handling in the systems of the gripping type on the other hand, can be combined in one system, when the beam path defined by an X-ray source and an X-ray detector of an X-ray device is perpendicular to the transport direction and the pivoting of the wheel is performed about a pivot axis which lies substantially in the transport plane.
  • the displacement of the pivot axis into the transport plane requires less space for the X-ray inspection device and, moreover, enables a pivoting range of 360 °.
  • the systems of gripping technology there are enormous time savings in terms of the test times, since the wheel does not have to be lifted out of the transport plane.
